A few suggestions, not for better search results, but these will help get guests who view your page to book - your first 5 photos should show an array of views, because when viewing on a laptop or desktop, all 5 are visible at the same time. 

We still get the odd theft from time to time but it's easy keeping a finger on the pulse when we only do 3-4 rehabs per month or so.Just had one recently but couldn't tell you when it happened prior to that.It's just the nature of the beast and could happen anywhere.At least we don't get car windows smashed by junkies and bags stolen from cars in broad daylight like in San Fran haha

If you want broad lists unfiltered, just tell him.   

I think the question is probably too broad to answer. 

Zillow's API is no longer offered (or they make it extremely hard to access these days - have had no luck finding an updated link/page for it), Redfin has broad-stroke CSVs you can download that only give 5-10 fields of info and not often at the metro area, you can't legally create a tool to crawl these websites...I'm looking for 1 (or a handful of sources) to pull together basic metrics at the metro/city level for US real estate.

Broadly speaking, there are two types; offsite (like SFR, small apartments, etc) and onsite (large apartments with leasing offices on the property).For offsite, I usually see 8-10% of collected rents, half or all of late fees and 1/2 to all of the first month's rent. 

In the case of property, the value you get is measured more broadly than in dollars of bricks and mortar.

To make broad generalizations or assumptions about entire quadrants of the city being "problem areas" is an error in judgement, in my opinion.Now, there are areas on the west side that I definitely try to avoid, but if I have to go there, I make sure to do it in the morning hours when most of the delinquents are sleeping.

Was driving by home this time last year and saw a FSBO ...

I would pay them again in a heartbeat because of the added value of weather protection on the home.I would look into a couple more quotes to give you a broad range, which might make you feel more comfortable in whatever direction you go.
